x86/efi: Clean up a minor mistake in comment

EFI allocates runtime services regions from EFI_VA_START, -4G, down
to -68G, EFI_VA_END - 64G altogether, top-down.

The mechanism was introduced in commit:

  d2f7cbe7b26a7 ("x86/efi: Runtime services virtual mapping")

Fix the comment that still says bottom-up.
